Estou trabalhando num projeto em java web com servlet e mysql, quando o mesmo se encontra no localhost funciona perfeitamente, porem quando subo o projeto para um servidor profissional o programa funciona por alguns minutos depois da o seguinte erro:
Caused by: com.mysql.cj.exceptions.CJCommunicationsException: The last packet successfully received from the server was 372,718 milliseconds ago. The last packet sent successfully to the server was 372,719 milliseconds ago. is longer than the server configured value of ‘wait_timeout’. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property ‘autoReconnect=true’ to avoid this problem.
alguém consegue ajudar?
